HAY-CARRIER.

Specification of Letters Patent.

Patented Nov. 6, 1906.

To all wh/0m. it muy concern:

Be it known 'that I, HENRY L. FERRIS, a citizen of the United States offLnerica, residing at Harvard, in the county of McHenry and State ofIllinois, have invented certain new and useful Improvements inHay-Oarriers, of which the following is a specification.

My invention relates to certain new and useful improvements in ha-carriers; and its object is to produce a device of this class whichshall have certain advantages, which will appear more fully and at largein the course of this specification.

To this end my invention consists in certain novel features ofconstruction, which are illustrated in the accompanying drawings anddescribed herein.

In the aforesaid drawings, Figure I is aside elevation of my improvedhay-carrier. Fig. 2 is a transverse vertical section in the line 2 2 ofFig. l, the fork-pulley block being shown in end elevation. Fig. 3 is aview, partly in side elevation and partly in vertical longitudinalsection, the line of section being indicated in the line 3 3 of Fig. 2.Fig. I is a yhorizontal section in the line 4 4 of Fig. l.

Fig. 5 is a view, partly in plan and partly in horizontal section, theline of section being indicated at 5 5 in Fig. 1. Fig. 6 is an invertedlan view of the carrier with the forkpulley lock removed. Fig. 7 is aperspective view of certain operating-dog, and Fig. 8 is a similar viewof the latch.

Referring to the drawings, A is a suitable track upon which runs acarriage B, supported by rollers b. This carriage terminates at itslower end in a circular turn-table B,

-which furnishes a pivotal support for a frame O. The sides of thecarriage B are cast with vertical channels b, in which channels isguided a locking-dog D. This dog is in general U-shaped in form (seeFig. 7) and is provided with laterally-projecting lugs d, which run inthe channels b. The lower portion of the dog has a pin d', the urpose ofwhich will be presently explained? and is provided with twoinwardly-extending beveled lugs d2, which engage with a tripping-block Aon the track. This tripping-block is of well-known construction and isprovided with a beveled liange a to engage with the lugs d2 to raise thelocking-dog and with flanges a', which engage therewith, to preventmovement if the carrier on the track when the locking-dog is raised, aswill hereinafter be explained.

At the longitudinal center of the frame C is journaled a latchE,swinging on a horizontal transverse axis in the form of gudgeons e4.This latch has a cam-surface, one portion e of which is circular and theother portion e of which is straight and nearer the pivot of the latchthan the portion e. Inasmuch as the latch is journaled in the center ofthe carriage B, the pin d on the locking-dog always bears against thiscam-surface, no matter how thelframe may be rotated with respect to thecarriage. When the latch is in the position illustrated in Fig. 3, thelocking-dog will be held up by engagement of the pin With the circularportion of the cam 3 but when the latch is rotated to the position shownin dotted lines in Fig. l the pin will run off the curved portion e ontothe surface e', and the dog will thus fall from the position shown inFig. 3, at the same time A reventing the reverse rotation of the latcuntil the dog is raised by some mechanism-as, for instance, thetripping-block.

The frame O is provided with a flaring mouth C at its lower end, thesame terminating in avertical groove adapted to receive ro'ectin ins onan u wardly-projecting ybke clin tljife fork-pulley block F. Thefork-pulley block F is supported by a rope g, running over pulleys G,mounted in the frame O.

The latch E is provided on its lower side with a hook e2, normally outof the line of the grooves c, and with an arm e3 in the line of saidgrooves. As the fork-pulley block is raised by pulling up the rope g theyoke on the forkepulley block passes into the Haring mouth of the frameC and the pins enter the grooves c. Eventually the top of the yokeengages the arm e3, rotating the latch, so that the hook e2 swingsunderneath the upper end of the yoke f As this rotation is continued thelocking-dog runs off the surface e on the latch, as before explained,thus releasing the carriage and permitting it to move longitudinally onthe track and simultaneously locking the latch in the positionillustrated in dotted lines in Fig. l to hold the fork-pulley block inits raised position. On the other IOO Vstrikes the tripping-block A itis raised, as

above set forth, releasing the latch, which is swung to the positionshown in Fig. 3 by the weight of the fork-pulley upon it. The forkpulleyblock is thus left free to fall by its own weight.

In a device of this class the most important features are cheapness ofconstruction, which means, of course, a small number of operating parts,simplicity in operation, and compactness, especially verticalcompactness, when the load is raised. These features are all combinedin. my improved device in the most advantageous manner. A single latchis used to hold the fork-pulley, and the dog which locks the latch inposition is operated directly by the tripping-block on the track, sothat only two movable parts are comprised in the locking mechanismproper. Furthermore, no riveting or other means for securing theoperating parts together is necessary.

To use a single latch, as I do, it-is necessary that the same take holdof the fork-pulley from above, and structures of this sort haveheretofore been open to the objection that the eye at the upper end ofthe fork-pulley was made so long as to sacrifice vertical compactness.In my device, however, the mouth at the lower end of the frame is madesufficiently large to receive the entire fork-pulley, and the eye whichis engaged by the latch is short enough that the latch lies within thegroove of the pulley, (see Fig. 2), thus producing a device with asinO'le latch which is as short vertically as any of the prior devices.This feature of vertical com actness is particularly desirable, becausetliese devices are often placed in barns having small openings, and itis very necessary that the load be held as close as possible to thetrack in order that a large load may be taken. It should be noticed thatthe arrangement of parts is such that the fork-pulley block is free toswing between the pulleys G when it is supported by the latch E.

I realize that considerable variation is possible in the details of thisconstruction without departing from Ithe spirit of my invention, and vIdo not, therefore, intend to limit myself to the speeic form hereinshown and described.

I claim as new and desire to secure by Letters Patentl. In a device ofthe class described, the combination with a track and a trippingblockthereon, of a carriage movable on the track, a frame swiveled to thecarriage, a fork-pulley block .having an upwardly-projecting yokearranged to be guided by grooves in the frame, a single latch pivoted ona transverse horizontal aXis, a hook on the latch, adapted to engagesaid yoke and to lie within the groove of the pulley of the fork-pulleyblock when the same is raised,v an arm on the latch lying in the path ofsaid yoke and arranged to be engaged thereby, and a dog adapted to bearagainst said latch and to engage with a depression therein.

2. In a device of the class described, the combination with a track anda trippingblock thereon, of a carriage movable on the track and having aturn-table at its lower end, a frame swiveled to the turn-table, asingle latch journaled in the frame on a horizontal transverse aXis, acam-surface on said latch projecting through a perforation in theturn-table, a dog guided in the carriage and bearing directly againstthe cam-surface, a fork-pulley frame having an upwardly-projecting yoke,an arm on the latch adapted to be engaged by the yoke and a hook on thelatch adapted to engage the yoke when the latch is rotated.

3. In a device of the class described, the combination with a carriagehaving a centrally-disposed turn-table and adapted to run upon asuitable track, a locking-dog guided to move vertically above the centerof said turn-table, said turn-table being perforated for the passage ofthe dog, a frame swiveled i to the turn-table, a single hook pivoted tothe frame and having a portion adapted to engage directly with said dog,and an engagement device on said hook adapted to coperate with afork-pulley, said engagement device being out of the vertical line ofthe dog whereby the load is supported eccentrically. In witness whereofI have signed the above application for Letters Patent, at Harvard, inthe county of McHenry and State of Illinois, this 21st day of September,A. D. 1904.
